You'll not only appreciate our Nashoba EK waterproof work boots as they provide the protection and comfort you need for a hard day on the job, but for their quality features as well. Their uppers are made with premium Timberland waterproof regenerative leather from farms that utilize ranching practices that help build heathy soil, plus breathable, moisture-wicking linings made of ReBOTL material containing at least 50% recycled plastic. An internal membrane provides maximum waterproof protection and blood-borne pathogen resistance. For safety, there are strong CarbonShield composite safety toes and built-in protection from electrical hazards. For all-day comfort, we added our Anti-Fatigue Technology footbed for shock absorption and energy return and a lightweight, All-Weather TPU outsole that offers heat-, oil-, slip-, and abrasion-resistant traction.
